Cholestatic hepatitis as a possible new side-effect of oxycodone: a case report

<p>Abstract</p> <p>Introduction</p> <p>Oxycodone is a widely-used semisynthetic opioid analgesic that has been used for over eighty years. Oxycodone is known to cause side effects such as nausea, pruritus, dizziness, constipation and somnolence. As far as we are aware cholestatic hepatitis as a result of oxycodone use has not been reported so far in the world literature.</p> <p>Case presentation</p> <p>A 34-year-old male presented with cholestatic jaundice and severe pruritus after receiving oxycodone for analgesia post-T11 vertebrectomy. Extensive laboratory investigations and imaging studies did not reveal any other obvious cause for his jaundice and a liver biopsy confirmed canalicular cholestatis suggestive of drug-induced hepatotoxicity. The patient's symptoms and transaminases normalised on withdrawal of oxycodone confirming that oxycodone was the probable cause of the patient's hepatotoxicity.</p> <p>Conclusion</p> <p>We conclude that cholestatic hepatitis is possibly a rare side effect of oxycodone use. Physicians should be aware of the possibility of this potentially serious picture of drug-induced hepatotoxicity.</p

Life-threatening acute acalculous cholecystitis in a patient with renal cell carcinoma treated by sunitinib: a case report

<p>Abstract</p> <p>Introduction</p> <p>Sunitinib, an oral multitargeted tyrosine kinase inhibitor, is widely used in the treatment of renal cell carcinoma and gastrointestinal stromal tumor and has had a variety of adverse events. However, sunitinib-related acute cholecystitis has been reported in only two patients with gastrointestinal stromal tumor and renal cell carcinoma (clear cell subtype).</p> <p>Case presentation</p> <p>A 75-year-old Japanese woman with a right sided abdominal swelling was referred to our hospital. Computed tomography (CT) showed a hypervascular bulky tumor in her right kidney, suggesting right renal cell carcinoma in clinical T4N0M0. Although sunitinib therapy was started as neoadjuvant chemotherapy, during the fourth week of the first cycle, she developed acute acalculous cholecystitis and disseminated intravascular coagulation associated with sunitinib. Sunitinib therapy was discontinued immediately and she recovered after subsequent treatment with antibiotics and gabexate mesilate followed by percutaneous cholecystostomy. Cholecystectomy and right radical nephrectomy were performed and pathological examination showed that her renal tumor was a chromophobe renal cell carcinoma (pT2) with necrosis. Inflammation and ischemia were observed in the gallbladder wall, which was compatible with acute acalculous cholecystitis. There has been no evidence of disease recurrence for more than six months.</p> <p>Conclusion</p> <p>We described the third case of sunitinib-related acute cholecystitis in a patient with chromophobe renal cell carcinoma. Attention is required to sunitinib-related acute cholecystitis which, while uncommon, could be life-threatening.</p

Carbamazepine overdose after exposure to simethicone: a case report

<p>Abstract</p> <p>Introduction</p> <p>Carbamazepine is an anticonvulsant drug and is also used as a treatment for patients with manic-depressive illness, post-herpetic neuralgia or phantom limb pain. The drug itself has many drug interactions. Simethicone is an antifoaming agent and is reported to be an inert material with no known drug interaction with carbamazepine.</p> <p>Case presentation</p> <p>We present a case of a patient who was routinely using carbamazepine 400 mg three times per day and levetiracetam 500 mg twice daily, and experienced carbamazepine overdose after exposure to simethicone. After cessation of simethicone therapy normal drug levels of carbamazepine were obtained again with the standard dose of the drug. The mechanism of interaction is unknown but the risk of overdose should be considered when prescribing simethicone to a patient who is using carbamazepine.</p> <p>Conclusion</p> <p>Simethicone and carbamazepine, when taken together, may be a cause of carbamazepine toxicity. The risk of carbamazepine overdose should be considered when prescribing simethicone to a patient who is using carbamazepine.</p

Association between isotretinoin use and central retinal vein occlusion in an adolescent with minor predisposition for thrombotic incidents: a case report

<p>Abstract</p> <p>Introduction</p> <p>We report an adolescent boy with minimal pre-existing risk for thromboses who suffered central retinal vein occlusion associated with isotretinoin use for acne. To the best of our knowledge, this is the first well documented case of this association.</p> <p>Case presentation</p> <p>An otherwise healthy 17-year-old white man who was treated with systemic isotretinoin for recalcitrant acne was referred with central retinal vein occlusion in one eye. Although a detailed investigation was negative, DNA testing revealed that the patient was a heterozygous carrier of the G20210A mutation of the prothrombin gene. Despite the fact that this particular mutation is thought to represent only a minor risk factor for thromboses, it is probable that isotretinoin treatment greatly increased the risk of a vaso-occlusive incident in this patient.</p> <p>Conclusion</p> <p>Isotretinoin use may be associated with sight- and life-threatening thrombotic adverse effects even in young patients with otherwise minimal thrombophilic risk. Physicians should be aware of such potential dangers.</p
